Travers is a drum MONSTER- i was just watching the Mike Keneally "Bakin' @ The Potato" DVD earlier, and Joe kills on that recording.
He also has a "dream job" serving as vaultmeister for the Zappas...
No doubt! Have you see the Classic Albums DVD of FZ's Overnite Sensation/Apostrophe'? Joe does a mini tour of the vault and it's awe inspiring for any Zappa fan.
Haven't seen it
But i remember a bio on Frank on A&E many years ago where they had some footage from inside the vault- incredible how much FZ was able to get documented, and saved.
